Fastest 25 m swim (MP4) (female)

The fastest 25 m swim (MP4) (female) is 36.80 seconds, achieved by Lily Brasch (USA) in New York, New York, USA, on 6 March 2024.

Lily has muscular dystrophy which impacts mobility in her arms and legs.

"I am committed to inspiring others by participating in challenges that might seem impossible to many. Despite my difficulty with climbing stairs, I have found strength and confidence in swimming, which led me to choose this event for my Guinness World Records challenge."

She trained for 8 weeks in preparation for the attempt and picked 6 March as it holds special significance for her. "This is the day I declared my physical independence after climbing Camelback Mountain on March 6th, 2022."
